Presenting a series of brief overviews of the DSA and its Bulletin across each “duodecade” or set of dozen issues. These overviews are strictly those written by the present Editor, one who didn’t have the pleasure of knowing the Founders nor the preeminent players of the “classic” Society. In this regard, the following overview is somewhat “non-canonical”: for a history of the DSA seen through someone who knew the early Members and Founders, read Prof. Gene Zirkel’s history. To get an inside look at the foundation of the Society, check out F. Emerson Andrews’ article “How We Began”, focusing on the pre-establishment years, at Vol. 9 pages 3-9.
The relatively recent membership of the present Editor offers a more detached viewpoint that may be of some use and interest. What follows is a synopsis of the development of the DSA as seen from a newly-joined Member (11XE;). This is a viewpoint of someone born when the DSA was two dozen two years old, familiar with the early Society mainly through its Bulletin, having scanned, processed, and read its 2058; pages and roughly one third of the 960; pages of the British publications to make this Digital Archive in the summer of 11E6;. Enjoy the story and write in with comments :).

In this first dozen issues, Editor Ralph Beard establishes the “classical” numerals for digits ten and eleven (the “transdecimal” numerals), and basic dozenal facts are explored. Mathematical constants, new measurement systems, cheerful correspondence from the World War II front lines roll into the Bulletin. Expertly drafted figures in “Kin of The Golden Mean” seem to detail the exacting love some felt for the new cause. Dozenalists revel with enthusiasm in their new organization. Some folks like Messrs. Elbrow and Robertson submit all-encompassing dozenal systems of thought. Others like Mary Lloyd pose teasers, games, even poetry and song about the dozen. It seems, near the end of this first duodecade, that the “first generation” of DSA Members are in on the ground floor of a new, practical, and amazing mathematical tool: the dozen! Continue »
